Table 1.
Home range size and core estimates for nine P. volans and ten P. minor calculated using the fixed kernel method at 95% isopleth and the minimum convex polygon method.
Table 2.
Results from linear models with home range size (at KUD 95%, KUD 75%, KUD 50% and MCP 95%) each as the response variable and species and sex and the interaction between species and sex as the explanatory variable.
Post-hoc comparisons between P. volans and P. minor were done at the KUD 95%, and 50% isopleths and MCP at the 95% isopleth.

Home range overlap between individual greater gliders.
Overlay of KUD home range areas at 95% isopleth (light shades) and core 50% isopleth (bold shades) a.) P. minor-Eastern Site (Taravale): adult male (TG11, blue) and adult male (TG4, green). b.) P. minor-Eastern Site (Taravale): adult female (TG5, yellow) and adult male (TG11, blue). c.) P. volans-Western Site (Wombat): three adult females (WG2, yellow; WG1, purple; WG4, pink). d.) P. volans-Eastern Site (Wombat): adult female (WG2, purple) and adult male (WG3, blue).

Comparison of tree species available to percentages of species selected for foraging and shelter in each cite: P. minor Eastern site (Taravale), P. minor Western Site (Blackbraes) and P. volans Eastern Site (Bendoc) and P. volans Western Site (Wombat).
Black bars are the percentages of each tree species in survey plots (total n per study area = 466, 432, 1280, 1046, respectively). Dark grey bars are the percentages of each tree species used as feed trees (total n per study area = 102, 94, 46, and 70, respectively). Light grey bars are the percentage of each tree species used for dens (total n per study area = 21, 17, 13, and 16, respectively).
Fig 4.
Comparison of the percentage of live trees available in each of 5 DBH categories (7–30 cm, 30-50- cm, 50–70 cm, 70–90 cm, > 90 cm) in survey plots to the percentage of trees of each size used as feed trees and for shelter at each site.
Black bars are the percentages of trees available in survey plots in each DBH category (total n per study area = 466, 432, 1280, 1046, respectively). Dark grey bars are the percentage of trees in each DBH category used for feed trees (total n per study area = 102, 94, 46, 70, respectively. Light grey bars are the percentage of trees in each DBH category used for dens (total n per study area = 21, 17, 15, 16, respectively).

Relationship between Petauroides home range size and the den tree biomass of survey plots.
Home range size is measured in hectares and biomass is measured in kg/hectare.
